Hi, Alex.
Excellent and convincing example of the point in question. Clarity is a
beautiful thing, is it not? I will be the first (well, maybe the second or
third) to admit that my stubbornness sometimes puts clouds between me and it.
To one point you made, especially in light of the privacy issue associated with
medical records, I should like to respond in particular. You said, “I know, the
Shared Folders are not literally "shared" on a network, it's an abstraction
that multiple OSes can handle, after installing the Guest Additions.” I am not
sure whether you had a chance to see one of my comments concerning the
accessibility of shared folders to others. This is not simply my opinion but
comes straight from the manual: “"If any host folder is shared with the guest
then a remote user connected to the guest over the network can access these
files too as the folder sharing mechanism cannot be selectively disabled for
remote users."
Thanks.

Subject: Re: [VBox-users] File transfer to host(SOLVED)
@John a better explanation, or use case, of USB pass-through that I've used in
the past, is to connect USB devices such as printers, or other specialized
hardware that cannot be used on the host, or is desired to use in the guest.
For example, one of my clients is a physician, and she uses a specialized
medical device for treating her patients, and the drivers and software needed
to run it does not work under 64-bit Windows. What I did is set up a VirtualBox
VM with Windows XP 32-bit inside, set up USB pass-through for the device, and
shared folders for documents, data files and reports to transfer through to the
host OS. As far as I know, the Shared Folders are not literally "shared" on a
network, it's an abstraction that multiple OSes can handle, after installing
the Guest Additions.
Another advantage of shared folders over a flash drive is that you're not
limited to the USB device's I/O performance limitations. In addition, the USB
pass-through feature is not available in VirtualBox OSS, only under the PUEL or
otherwise licensed VirtualBox. I don't know if the latter applies to you.
Now if you're trying to copy to another host, OUTSIDE of the virtual machine,
perhaps using the OS file sharing capabilities would be better suited to your
needs.
Had the shared folders capability not been offered, I could understand why this
would be a useful task.

I return to my original qualified statement after all, if I were to hear a
"good" reason or compelling explanation as to why it is not a viable solution
to make use of the USB pass-through feature Oracle built into Vbox, I will
continue to use it as I have been when I find it suitable to my needs. Security
is a major consideration of mine and not creating shared directories when not
necessary is a tenet of best practices from a security standpoint. Being
convenient is hardly a good reason.
